Title: Inductive thin film magnetic head
Inventor: SAKA CHIAKI
IPC: G11B5/31
Filed: 1988-01-13
Abstract: PURPOSE:To take a stable magnetic domain structure, to reduce a waveform distortion and to increase a reproducing output by constituting the plane form of a magnetic core so as to have the angle of about 90 deg. formed by the end of a magnetic pole and a back core. CONSTITUTION:The plane form of the magnetic core is constituted so as to have the angle of about 90 deg. formed by the end P of the magnetic pole and the back core B. In such a way, the magnetic domain structure of the magnetic core is a magnetically stable circulating magnetic domain structure. The magnetic domain structure indicating a magnetic domain wall by the heavy line in the drawing is obtained by a bittering method. In the vicinity of the boundary of the end P of this magnetic pole and a back area B, a stable 180 deg. magnetic wall W substantially parallel to a medium is formed and an unstable triangular magnetic domain S is formed at a part remote from the end part, so that the stable magnetic domain structure is formed as a whole. Thereby, a magnetization is a simple operation to reduce the waveform distortion and increase the reproducing output.

Title: Substrate for reflection type liquid crystal cell, and reflection type liquid crystal display device using the substrate
Inventor: KAMEYAMA KENJI
IPC: G02F1/1335
Filed: 1999-01-11
Abstract: PROBLEM TO BE SOLVED: To provide a substrate for a reflection type liquid crystal cell which shows no decrease in the reflectance and which does not require a sticking process of a reflection plate, by forming a rugged reflection layer having a rugged pattern and a reflection layer on the surface of a substrate opposite to the surface to be in contact with a liquid crystal layer. SOLUTION: A rugged reflection layer 9 having a rugged pattern and a reflection layer is formed on the surface of a substrate 5 opposite to the surface to be in contact with a liquid crystal layer. The rugged reflection layer 9 reflects the light entering at a specified angle to the normal line direction of the liquid crystal panel to produce a diffused state. In the production process of the reflection layer 9, the surface profile is transferred to the back side of the substrate where electrodes to drive the liquid crystal are to be formed, electrode films are formed, and the electrode pattern is formed in a photolithographic process, and finally the reflection layer 9 is formed. By this method, since the reflection layer 9 is directly formed on the substrate, decrease in the reflectance can be avoided and no adhesive is required.  Thus, a process to stick a reflection plate to a liquid crystal panel is made unnecessary and the production yield can be improved.

Abstract: PROBLEM TO BE SOLVED: To feed and discharge a part while directing in the same direction at all times by discharging a part through a first air supply means when it is directed correctly and discharging a part through a second air supply means when it is directed reversely thereby directing the part correctly. SOLUTION: Direction of a part 1 passing through a shoot 7 is detected by a part decision sensor and that information is inputted to a control section. When the part 1 shifted to the position of a pass hole 30b is directing reversely, an index ring 16 is turned by means of a motor 17. When the part 1 is shifted to a pass hole 30e, a solenoid valve 26 is opened to supply the air from a duct 25 thus discharging the part 1 to a discharge port 28 in the reverse direction. When the part 1 is directed correctly at the pass hole 30b, a solenoid valve is opened as is and the part 1 is discharged to the discharge port 28 through a part bypath 21. Consequently, the part 1 can be discharged in the same direction as it passes through the shoot 7.

Abstract: PURPOSE: To make a service cage reach in accordance with the prearranged time of reaching, by inhibiting the reopening of a door of a 2nd platform when a reaching delay detecting circuit, which detects a fact that reaching may be later than the prearranged time of reaching computed, operates.  
     CONSTITUTION: Supposing platform descent calling is registered at a 5th story, and a No.1 machine stopping at a 1st story is assigned for the calling. When a service cage is assigned, a reaching expected time computer A computes the expected time of the reaching of the cage at that point of time, and the value is displayed to a reaching prearranged time device B in the descent direction of the 5th story. When the expected time is larger than the prearranged time, the reopening of a door is inhibited by a 5th story descent calling reaching delay detecting circuit 5Dd, the door is shut and the cage starts in order to respond to the descent calling of the 5th story. Thus, the door is not opened and the cage is early started even if a platform button of the 1st story where the cage stays is depressed when the cage may be later than displayed reaching prearranged time.
